JOHN J. VAN IDERS'IINE, OF KANSAS CITY, MISSOURI.

VEHICLE-WHEEL.

Application filed January 2 To all whom it may concern Be it known thatI, JOHN J. VAN IDER- sriivn, a citizen of the United States, residing atKansas City, in the county of J ackson and State of Missouri, haveinvented certain new and useful Improvements in Vehicle-Vheeis, of whichthe following is a specification.

My invention relates to improvements in vehicle wheels.

The object of my invent-ion is to provide a device which may be readilyand securely attixed to an ordinary wagon or carriage wheel, and whichwill have the resiliency and other advantages of an inflatable pneumatictire, but which can not be punctured.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred form of myinvention, Figure 1 is a view partly in side elevation and partly invertical section of a wheel having mounted on it my improved attachment.Fig. 2 is an enlarged cross section view on the line (a -b of Fig. 1.

Similar reference characters designate similar parts in the difierentviews.

1 designates the tire, 2 the felly and 3 the spokes of an ordinarycarriage or wagon wheel.

Encircling the tire I and detachable therefrom is a rim which comprisespreferably an annular tubular body a which encircles but is spaced apartfrom the tire 1, the body having an annular inwardly extending flange 5disposed at one edge of the tire 1, and a ring 6 secured to the body 4by any suitable means, such as bolts mounted in the body 4e andextending through the ring 6 and designated by 7, the bolts havingmounted thereon nuts 8 which bear against the outside of the ring 6. Thering 6 is disposed parallel with the flange 5 at the other edge of thetire 1.

The rim is provided with radial tubular guides 9 which extend outwardlyfrom the channel formed by the body, the flange 5 and ring 6.Respectively mounted in and extending through the tubular guides 9 arecoil springs 10 the outer ends of which bear against the inner wall ofthe body 4, and the inner ends of which extend into the channel and bearagainst and are slidable upon the periphery of the tire 1. By having theSpecification of Letters Patent.

Serial No. 668,848.

radial springs 10 slidable on the tire 1, the springs, when in thehorizontal position can move vertically over the tire 1 so as to permitthe movement vertically of the wheel within the rim. As shown the innerends of the springs 10 may be mounted in suitable containers comprisingcups 11 which are slidable on the tire 1.

The periphery of the body 4 may be provided with an annular groove 12 inwhich may be mounted a yielding rubber tread or tire 13. The groove 12may be of the clencher type, the side walls of the groove being inwardlyturned to more securely hold the tread or tire 13.

As the springs which are in position to support the weight of the wheelare compressed thereby, the springs which at the time are horizontallydisposed will be free to permit the relative vertical movement betweenthe wheel and attachment, inasmuch as the springs are not fixed at theirinner ends to the tire 1. If it is desired for any reason to detach therim from the wheel, the nuts 8 are removed from the bolts 7, after whichthe ring 6 may be detached from the body 4, thus permitting the body tobe detached from the wheel.

I do not limit my invention to the struc ture shown and described, asmodifications, within the scope of the appended claim, may be madewithout departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

In a vehicle wheel, a tire, a rim encircling the tire and having anannular tubular body, radial tubular guides extending outwardly from theinner side of the body and means for slidingly engaging opposite edgesof the tire, and coil springs extending respectively through saidtubular guides and having their outer ends bearing against the innerwall of said body, and their inner ends bearing against and slidableupon the tire.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
